Hi guys. Should I adjust the plug gap on my 6M turbo at all? Or should I leave it in the factory position? Not sure if it'll make that much of a difference but I know the plug gap is different on the turbo motor.

I've heard that old muscle car performance guys would run a slightly larger gap... said to increase the power of the spark since it has to travel further to the more distant electrode... therefore the potential energy is increased...

YMMV.

I always leave the OEM gap, seem to get me the best performance. More gap requires more potential voltage to jump the gap, unless you run MSD, I dont recommend it.
